Last summer we introduced the companion idea (AddSquareTrip) to today's concept. It would probably be a good idea to review that one first, if you haven't done so recently. Today we'll add a little twist to that process--which means we have a whopping 2 or 3 steps to do to solve these. This concept appeared 9 times last year, with a median placement at question # 67.

These questions are usually pretty easy to identify--examples coming shortly. Once you have recognized the pattern, follow these steps:
- Square the smaller number.
- Multiply the result by 5 (or divide by 2 and multiply by 10).
Example 5: 32 x 32 + 16 x 16 = ___
- This is a very clever disguise. Notice that this problem is actually the same as Example # 2, only written as a multiplication (instead of squaring), and with the larger number first.
- Square 16 to get 256.
- Multiply by 5 to get 1280.
